Pond Ecosystem:

Blacks Nook Pond

By cougargirlohyeah and group

Introduction

I am a 6th grade student in the Amigos School in Cambridge, Massachusetts. We are doing a project on the ecosystems in the Boston area. My group is researching the pond ecosystem and we are using Blacks Nook Pond by Fresh Pond in Cambridge as an example.

ABIOTIC OBSERVATIONS

The abiotic or non-living things in this ecosystem are: Air (oxygen and carbon dioxide) at 62 degrees farenheit in October 2006, fresh water at 68 degrees farenheit and with the pH of about 6 or 7 also in October, earth (rocks, sand, and dirt), and… The sun!

BIOTIC ORGANISMS

The biotic or living things we found were producers: algae, duckweed, plant-like plankton, elodea and bacteria; herbivores: phantom midge larva, damselfly nymph, threadworms, copepod, flatworms, animal plankton and turtles; carnivores: mosquitoes, leeches, threadworms, turtles, frogs, heron, fish, flatworm; and decomposers: thread worms, flatworms,and bacteria

This is the list we made of the things you will find in the pond.



This is a picture from when the 8th graders went to the pond, on our trip we had forgotten the camera.



This is an energy pyramid showing the sun, decomposers, producers, primary consumers (herbivores),
secondary consumers (carnivores), and the tertiary consumers (also consumers).
